SHEET PILE.

Application filed September 20, 1923.

This invention relates to improvements in sheet piles. By the use of myimproved sheet piles it is possible to make a very tight wall such as isused in making caissons, cotter-dams, retaining walls and the like. Myimproved piles may be easily driven or otherwise put into position andare so constructed that in driving a pile it will stay close to theadjacent pile. l Vith many other forms of sheet piles it is verydir'licult to keep the lower ends from separating. My improved piles arealso provided with means for interlocking the lower ends after the pilesare in position. Other features and advantages 01 my sheet piles willappear as I proceed with my specification.

In that form of device embodying the features of my invention shown inthe accompanying drawings,

Fig. 7 is a view taken as indicated by the line 7 of: Fig. 6, and

Fig. 8 is a bottom plan View of the end of one of: the piles.

As shown in the drawings, 10, 10 indicate sheet piles adapted to bedriven adjacent each other to form sheet piling. Since the piles aresimilar, I will describe in detail but one. The pile 10 is here shown asmade of concrete. although it is obvious that it may be made of anyother suitable material. The concrete may be reinforced or not asdesired. The pile is substantially rectangular in shape and provided atone of its vertical side edges with a groove 11. This groove 11termmatesa short distance from the bottom of the pile Serial No.663,833.

as indicated by 11 and the corner is beveled as indicated by 12. Thelower edges of the front and back faces are also slightly beveled asindicated by 13. The opposite edge of the pile 10 is provided with twolongitudinal ridges 14L slightly concave between as indicated by 15. Thetwo ridges 14 are adapted to go into one of the grooves 11 of anadjacent pile when the piles are in position leaving a channel betweenthe piles substantially circular in cross section. After the piles arein position, this channel may be grouted or cemented or filled withcementt tious material in any desired manner in ore er to more firmlybond the piles together and make a tight joint.

At the bottom of the channel 11 there is mounted in the side of the pilea flat bar 16 which slants upwardly to form the pocket 16 at the bottomof the channel. The bar 16 is bent at 16 and its horizontal part asindicated by 16 is embedded in the concrete to hold it firmly inposition. The exposed end of the bar 16 which forms a pocket is alsosupported by a strap 17 which passes around the bar 16 and has. its endsas indicated by 17 embedded in the concrete to hold it firmly inposition.

The opposite side edge of the pile has near its lower end an outwardlyand clownwardly projecting hook or interlocking member 20 which is hereshown as T shaped in cross section in order to give rigidity. Thismember has its upper end embedded in the concrete of the pile and isadditionally supported by means of the strap 21 which extends around itand has its ends embedded in the concrete as indicated by 21*.

In setting a pile, the hook 2O slides down wardly in the channel 11until it engages with the member 16 and seats in the pocket 16*, thusinterlocking the lower ends of the piles. Two piles with the lower endsthus interlocked are clearly shown in Figs. 5 and 7.

The following means are provided for assisting in properly locating thepiles. The beveled corner 12 operates to assist in keeping the lower endof a pile close to the adjacent pile as it is being put into position.Besides this, it is to be noted each pile is provided with three jetholes as indicated by 80, 81 and 82. All of these jet holes communicatewith a common supply pipe 33 which opens at 34:. Any suitable means maybe used for introducing water under pressure into the opening 3%. Thejets from the holes 81 and 32 issue directly downwardly. The jet fromthe hole 30 issues downwardly and to the side toward the adjacent pilewhich was previously set. This from the hole 30, it will be noted, willtherefore direct a stream into the channel 11 of the adjacent set pileand keep this channel tree to permit the movement therein of the hookQ0. Issuing to the side and downwardly it will also remove allobstructions between the two piles and cause the lower end of thedescending pile to hug the next adjacent pile whichwas just previouslyset.

lVhile I have shown and described certain embodiments of my invention,it is to be understood that it is capable of many modifications.Changes, therefore, in the construction and arrangement may be madewithout departing from the spirit and scope of the invention asdisclosed in the appended claims, in which it is my intention to claimall novelty inherent in my invention as broadly as possible in view ofthe prior art.

What I claim as new and desire to secure by Letters Patent is: i

1. A sheet pile having a longitudinal groove at one edge, a taperedpocket at the lower end 01" the groove, and an interlocking member atthe lower end of the opposite edge, said interlocking member adapted totravel in the groove Oil an adjacent set pile as the pile is drivendownwardly and adapted to seat in the tapered pocket of said adjacentset pile as it reaches the end of the groove to draw the ends of thepiles together.

2. A sheet pile having a longitudinal groove at one edge, a taperedpocket at the lower end of the groove, and an interlocl-: ir-g member atthe lower end of the opposite edge, said interlocking member adapted totravel in the groove of an adjacent set pile as the pile is drivendownwardly and adapted to seat in the tapered pocket of said adjacentset pile as it reaches the end o1 the groove to draw the ends of thepiles together, said pile having a jet hole at the end adapted to issuea stream or" liquid into the groove of said adjacent set pile as thepile is driven downwardly.

3. A sheet pile having a longitudinal groove at one edge, a taperedpocket at the lower end of the groove, and an interlocking member at thelower end oi the opposite edge, said interlocking member adapted totravel in the groove of an adjacent set pile as the pile is drivendownwardly and adapted to seat in the tapered pocket of said adjacentset pile as it reaches the end of the groove to draw the ends of thepiles together, said pile having two jet holes at its lower end, one ofsaid jet holes adapted to issue a stream of liquid into the groove of anadjacent pile as the pile is driven downwardly and the other jet holeadapted to issue a stream substantially straight downwardly.

4. A sheet pile having a longitudinal groove at one edge, a pocket atthe lower end of the groove, an interlocking member at the lower end ofthe opposite edge adapted to travel in the groove of an adjacent setpile as the pile is driven downwardly and adapted to seat in said pocketas it reaches the end or" the groove, and a jet hole near the lower endof the pile adapted to issue a stream of liquid into said groove of:said adjacent set pile as the pile is driven do we w ardl y.

5. A sheet pile having a longitudinal groove at one edge, a pocket atthe lower end of the groove, an interlocking member at the lower end ofthe opposite edge adapted to travel in the groove of an adjacent setpile as the pile is driven downwardly and adapted to seat in said pocketas it reaches the end of the groove, said pile having a ct hole near thelower end adapted to issue a strean'i of liquid into said groove of saidadjacent set pile as the pile is driven downwardly, said jet hole alsoadapted to issue a stream of liquid into the pocket of the adjacent setpile as the pile being driven cars the end oi its travel.

In witness whereof, l have hereunto set my hand this 28th day of August,1923.
